The density in grams per litre of ethylene `(C_(2)H_(4))` at `STP` is :-

A

`1.25`

B

`2.50`

C

`3.75`

D

`5.25`

Text Solution

Verified by Experts

The correct Answer is:
A
`PV = nRT implies P = (rho)/(M_(w)) RT`
`implies rho = (PM_(w))/(RT)= - ((10^(5))(28 xx 10^(-3)))/(8.3 xx 273) kg m^(-3) = 1.25 g //litre`
